within the forest understorey. It ascends to higher perches (up to 1.5 m above the ground) to sing, and is most active and vocal in the hours following dawn and prior to dusk. It usually occurs in pairs, less often singly, and one group of three has been observed. Reproduction The males captured in February and March had enlarged testes, typical of breeding birds. The fledgling and an adult with old brood patches were observed in June. These data and song activity from February to April (a dry season) suggest that the breeding season begins early in the year, possibly as early as January, and extends for several months. As in other Grallaria species, the fledgling was less developed than those of most passerines, and both parents fed it earthworms. Conservation status The bird has a very restricted known range, limited to the Colibrí del Sol reserve and its immediate vicinity, while previous surveys in similar habitat in the region have failed to record the species. Moreover, habitat used by the bird has been extensively cleared for pasture, and the area is rich in minerals. The known population of 24 territories has an estimated area of , giving a conservative global population estimate of 57–156 territories. Both articles on the new species propose that the IUCN classify Fenwick's antpitta as critically endangered, and this will be followed in the forthcoming 2011 edition of the BirdLife International list, which is the authority used for birds by the IUCN. Although it is protected in the Colibrí del Sol reserve, it needs further protective measures. The single bird or pair that was known from outside the reserve has not been recorded since mid-2010 and appears to have disappeared. Controversy over the discovery The first description was published in Conservación Colombiana, the journal of Fundación ProAves. It was accompanied by an editorial giving the reasons that Diego Carantón, who discovered the bird, was not among the authors of the paper. The editorial accused Carantón of taking specimens illegally as well as violating his contract by omitting mention of his discovery from his monthly reports to Fundación ProAves and by trying to deprive the foundation of its intellectual property in the discovery. Specifically, it said that the Fundación had learned of the discovery through third parties in October 2008. Attempts to agree on a publication authored by Carantón and members of Fundación ProAves failed, and
